It was almost torn down in 1909, but was saved because of its antenna - used for telegraphy at that time. Beginning in 1910 it became part of the International Time Service. French radio (since 1918), and French television (since 1957) have also made use of its stature.During its lifetime, the Eiffel Tower has also witnessed a few strange scenes, including being scaled by a mountaineer in 1954, and parachuted off of in 1984 by two Englishmen. In 1923 a journalist rode a bicycle down from the first level. Some accounts say he rode down the stairs, other accounts suggest the exterior of one of the tower's four legs which slope outward.However, if its birth was difficult, it is now completely accepted and must be listed as one of the symbols of Paris itself.

There are several structures in Greece that archaeologists have called pyramids. Dotted throughout the landscape are remains of buildings that were described by ancient travelers as pyramids, they were first excavated by Americans and Germans in the early 1930s and the 1990s.Pausanias, a Greek traveler in the second century A.D. described several of the structures as pyramids. One of these pyramids was located in Helleniko, Ελληνικό in Greek,a village near Argos near the ancient ruins of Tiryns.[1] The story surrounding the monument was that it was built as a polyandria, a common grave, for those soldiers who had fallen in the struggle for the throne of Argos back in the 14th Century B.C. He described the structure as something that resembled a pyramid with the decorations of Argolic shields, showing the military connection to it. Another pyramid that Pausanias saw on his journeys was at Kenchreai, another polyandria dedicated to the Argives and Spartans who lost their lives at the Battle of Hysiai in 669 B.C. Unfortunately neither of these structures remain fully intact today to test how closely they resembled the pyramids of Egypt nor is there any proof that they even resembled an Egyptian pyramid at all.There are two surviving pyramid-like structures still available to study, one at Helleniko and the other at Ligourio, a village near the ancient theatre Epidaurus. With these two pyramid’s base stones remaining, it is possible to determine that Grecian pyramids existed, but were not used as the Egyptians used them. These buildings were not constructed in the same manner as the pyramids in Egypt. The buildings at Helleniko and Ligourio were no more than 100 feet tall and were surrounded by walls, with the base of the Helleniko pyramid being nine meters by 7 meters. The stone used to build the pyramids was limestone quarried locally and was cut to fit, not into freestanding blocks like the Great Pyramid of Giza. The base of the structures also differed from the Egyptian pyramids as they were rectangular, not square. This simple construction shape made it very difficult to make the top of the building come together in a point. As such, it makes more sense that these structures could have been peaked by a roof or platform.

The tombThe focus of Taj Mahal is the white marble tomb, which stands on a square plinth consisting of a symmetrical building with an iwan, an arch-shaped doorway, topped by a large dome. Like most Mughal tombs, basic elements are Persian in origin.Simplified diagram of the Taj Mahal floor plan.Main iwan and side pishtaqsThe base structure is a large, multi-chambered structure. The base is essentially a cube with chamfered edges and is roughly 55 metre on each side (see floor plan, right). On the long sides, a massive pishtaq, or vaulted archway, frames the iwan with a similar arch-shaped balcony. These main arches extend above the roof of the building by an integrated facade. On either side of main arch, additional pishtaqs are stacked above and below. This motif of stacked pishtaqs is replicated on chamfered corner areas as well. The design is completely symmetrical on all sides of the building. Four minarets, one at each corner of the plinth, facing the chamfered corners, frame the tomb. The main chamber houses the cenotaphs of Mumtaz Mahal and Shah Jahan with their graves located on lower level.Base, dome, and minaretThe marble dome that surmounts the tomb is its most spectacular feature. Its height is about the same size as the base of the building, about 35 metre and is accentuated as it sits on a cylindrical "drum" of about 7 metre high. Because of its shape, the dome is often called an onion dome (also called an amrud or guava dome). The top is decorated with a lotus design, which serves to accentuate its height as well. The shape of the dome is emphasised by four smaller domed chattris (kiosks) placed at its corners. The chattri domes replicate the onion shape of main dome. Their columned bases open through the roof of the tomb and provide light to the interior. Tall decorative spires (guldastas) extend from edges of base walls,and provide visual emphasis to the height of the dome. The lotus motif is repeated on both the chattris and guldastas. The dome and chattris are topped by a gilded finial, which mixes traditional Persian and Hindu decorative elements.FinialThe main dome is crowned by a gilded spire or finial. The finial, made of gold until the early 1800s, is now made of bronze. The finial provides a clear example of integration of traditional Persian and Hindu decorative elements. The finial is topped by a moon, a typical Islamic motif, whose horns point heavenward. Because of its placement on the main spire, the horns of moon and finial point combine to create a trident shape, reminiscent of traditional Hindu symbols of Shiva.[9]At the corners of plinth stand minarets, the four large towers each more than 40 metre tall. The minarets display Taj Mahal's penchant for symmetry. These towers are designed as working minarets, a traditional element of mosques as a place for a muezzin to call the Islamic faithful to prayer. Each minaret is effectively divided into three equal parts by two working balconies that ring the tower. At the top of the tower is a final balcony surmounted by a chattri that mirrors the design of those on the tomb. The minaret chattris share the same finishing touches, a lotus design topped by a gilded finial. Each of the minarets were constructed slightly outside of the plinth, so that in the event of collapse, a typical occurrence with many such tall constructions of the period, the material from the towers would tend to fall away from the tomb.
